There is some fantastic coaching happening in Milwaukee. Over the last handful of years, there have been multiple instances of catchers completely turning their defense around with the Brewers, with Omar Narváez the most notable example. The team’s latest success story is William Contreras. In his first 146 games with Atlanta, Contreras was a solid player with an exceptional bat. In 376 plate appearances in 2022, he had a 138 wRC+. That is a great mark for any hitter, let alone a catcher. However, his defense was lackluster across the board. The skills were there — that didn’t seem to be a major concern — but Contreras’ performance was below average when it came to framing, blocking, and throwing. It seemed like his defense might be a slow burn, but Milwaukee had another plan in mind.

To get an idea of how incredible Contreras has been so far, we will start with the numbers. You might be shocked when you see them because this isn’t a story of a catcher going from below average to average. This is the story of a catcher going from below average to top tier:

Are you confused? I’m confused. When I first saw these numbers, my jaw dropped. Catcher is the most physically demanding and difficult position on the field. To suddenly become one of the best at the position in a matter of months is inconceivable to me. Typically, a player will see improvements in one area one year, another in the next, and so on and so forth. Contreras didn’t have a typical ascent though. Instead, he did all of this practically overnight. His framing has moved from the 20th percentile last year to the 74th percentile this year. In 2022, he wasn’t even in the top 50 of blocking runs saved, but he now leads all catchers. Yes, that’s a better rate than J.T. Realmuto or Sean Murphy have managed. Lastly, his throwing has been good this year as well. Despite no real improvement in terms of his pop time, his CS% jumped from 7% to 33%. That is most likely due to significantly improved accuracy and footwork. So what gives? How in the world is he pulling this off?

I’ll start with blocking. A rapid improvement here makes more sense to me than framing. I say that because blocking is all about preparation, both pre-game and pre-pitch. Pre-game, you have to do the necessary work to understand your staff’s pitch shapes and tendencies. If this becomes back of the hand knowledge to you, then blocking in game is that much easier. Pre-pitch, you use that knowledge to determine your setup and decision making. After watching every pitch that Statcast labeled as a block for Contreras both last year and this year, it’s become clear to me that the improvement is rooted in Contreras no longer attempting to block right-handed breaking balls and offspeed pitches with his chest. Here is some video from 2022 to start:

All three of these pitches are standard blocking attempts. There isn’t a 30 foot spiked pitch or one with wicked side-to-side spin. Technically, they are all executed blocks since the runner doesn’t advance and they didn’t scoot far enough away to be passed balls. However, each of these locations should be areas that a catcher stuffs right in front of them. Now, let’s see what Contreras does this year in the face of right-handed breaking ball and offspeed pitches:

This is unorthodox! When I think of the great pickers, names like Yadier Molina, Francisco Cervelli, and Joe Mauer come to mind. But the weird thing is, they didn’t all exclusively pick! Usually there is a time and place where you just have to get your body in front of the ball, but for Contreras, his hand is the best possible extension of his body he could have. On spiked curveballs or side-sweeping sliders far in front of the plate, he is picking the ball with ease.

There were signs this was a special skill for Contreras last year — he picked countless nasty sliders from Spencer Strider all season. But it’s quite unorthodox to tell a catcher to completely sell out for this approach. However, if you’re confident enough in the scouting that says he has 80-grade hands and readability, then heck, just go for it! The early returns are quite promising too. You may think this is luck, but these four examples are representative of a skill that Contreras has shown to be repeatable all season no matter the pitcher or pitch shape.

Now, let’s move on to the other key part of catching directly related to smooth, strong hands: framing. If you can recall from the table above, Contreras’ strike rate has increased by 4.1 percentage points since last year, and his framing runs have increased by 5. The best opportunity for a catcher to make a big jump in framing is the bottom of the zone, from the middle of their body and away from their glove hand – and that has indeed been the point of focus and improvement for the Brewers backstop. Statcast defines these two zones as Zone 18 (middle-low shadow zone) and Zone 19 (arm side-low shadow zone). In Zone 18, Contreras’ strike rate has jumped from 43.6% to 62.7% (third in baseball). In Zone 19, it’s jumped from 20.3% to 29.7% (ninth in baseball). That’s another huge increase that warrants some video work. Here are six videos of pitches in Zone 18 – the first three are from 2022 and the second three are from 2023:

2022

2023

This trend was much easier to pick up on than the picking! Right away you can see that Contreras has changed his pre-pitch hand position. In 2022, his hands were stabby at the bottom of the zone. One crucial part of framing fastballs at the bottom of the zone is having a loose wrist as the pitch is being released. That slight quarter turn he did before the pitch wasn’t enough for him to keep consistent looseness between his wrist and elbow. Even when he did attempt a quarter turn (as with Kyle Wright’s sinker), it was off tempo and he still ended up bringing up his glove to the middle of his body before the pitch arrived.

In 2023, he has bought into a soft quarter turn that allows him to stay under the ball through reception. If you can stay under every single pitch, you can better manipulate the presentation of the ball. Pushing up through a fastball is much smoother than stabbing it and picking your glove back up. The best way for you to do that consistently is by making sure your glove always starts under the height of the shadow zone. It’s a simple concept that doesn’t require the catcher to take on a complete overhaul. Cue the right motions and targets, and the catcher will begin to understand what that reception should feel like. Contreras clearly now has that understanding and ability to execute every pitch.

As far as throwing is concerned, it’s not surprising to see early success for Contreras just from a mental point of view. If you’re confident in your receiving and blocking, then your mind is in a better place to execute solid mechanics and make an accurate throw. But I do have to point out how the improvement in framing can directly impact this as well. With a smooth motion from the ground up, your hands are in a better position to perform consistent exchanges. Stabbing at the ball brings your momentum back towards the ground, whereas a fluid motion starting from the ground lets you maintain a fluid motion towards your ear. It is all connected!

This early success is amazing for both Contreras and the Brewers. Last year, their two primary catchers were Victor Caratini and Narváez. Both were sub-90 wRC+ hitters despite their great catching. That led to 2.3 combined WAR on the year. Through 33 games (29 at catcher), Contreras has already accumulated 1.1 WAR. If he stays on that track, it will be a significant upgrade for the team. It’s an exciting development for both the club and a young catcher who looked like he might be an offense-first player behind the dish. Kudos once again, Milwaukee.

Position changes can be risky. The outcome depends heavily on the timing and circumstances of the switch, and the natural ability of the player. Sometimes, rookies need to carve out a roster spot for themselves and end up switching on the fly, like Jordan Walker. His shift to the outfield is a work in progress, just like it would be for most rookies. Then there are cases of a more experienced player moving due to roster construction, as with Jazz Chisholm Jr.’s move to center field.

Chisholm’s switch was precipitated by the Marlins’ offseason trade for Luis Arraez. With the sixth-worst offense (88 wRC+) in all of baseball in 2022 and good starting pitching depth, a pitcher-hitter swap to improve the lineup was highly logical, and the Marlins saw their best chance to obtain an impact bat in Arraez. That created something of an infield logjam. With Joey Wendle penciled in at shortstop and Jean Segura at third, the question became what they would do with their young star, who was slated to start at second base. Soon after the announcement of the trade, Kim Ng revealed that Jazz would be moving to center field, their most important position of need. His speed, athleticism, and lack of premium defense on the infield made it worth a try. Read the rest of this entry »

Recently, I wrote a piece about the benefits of hitters simplifying the mechanical process in their load or gather. For many hitters, moving too much in the lead-up to their barrel entering the hitting zone can create inconsistent timing and suboptimal reciprocal movements. Taking noise out of the swing can better prepare a hitter to have a consistent bat path; if you always know where your barrel is in space, you’re better equipped to hit the sweet spot more frequently. The thing is, not all hitters are the same. What works for one may not work for another, and that is the beauty of baseball.

I’m afraid I may have left some readers with the impression that simplification is the only path to improvement, when in reality, some hitters need to add more movement to their process to put their body in a position to be athletic. More movement does not always equal more complication if that movement is in the right direction. If a hitter stagnates their mechanics too much, they could be taking away from their potential. The kinetic chain needs flowing energy to function at full capacity. To some people, cueing simplicity and less movement can be harmful. Read the rest of this entry »

Sean Murphy does not get cheated when he swings. No matter the count, he is going to put up his A swing in hopes of barreling up the baseball. His profile is one of my favorites to watch. Although this type of hitter can be more prone to strikeouts than most, Murphy has managed to maintain a respectable strikeout rate in the last few seasons due to solid bat-to-ball skills and above-average plate discipline. Add solid raw strength on top of that, and you have yourself a career 116 wRC+ hitter. But this year, he has blown that mark away with a 182 wRC+ through 119 plate appearances. That’s an incredible jump that warrants some investigative work.

If I were a hitter looking to improve, I would focus on two things. The first is tweaking my mechanics to make myself less prone to exploitation. In other words, I’d make sure my bat path could cover different heights and depths of the zone so that I can be adjustable to different speeds and locations. The other approach would be to learn with what pitches and in which zones I’m already good at making flush contact and adjust my swing decisions to cater to those tendencies better. These two things are often intertwined, but depending on where a hitter is at in their career, they may focus on one more than the other or have an equal split.

For Murphy, it seems the focus has been more on matching his swing decisions to his strengths, and that has worked very well thus far. Below is a table with his swing rates by pitch type in the last few seasons:

This year, Murphy is swinging at fewer fastballs and breaking balls than he typically has, leading to an overall Swing% decrease. In 2021 and ’22, he swung at fastballs and breaking balls 47.6% and 49.3% of the time, respectively. This year, that number is down to 43.0%, the lowest since his best offensive year in the shortened 2020 season, where his Swing% was 41.3%.

The bulk of that change comes from not chasing as often. Murphy’s chase rate on fastballs and breakers have both seen notable drops. For somebody who had a chase contact rate of 61.1% in 2022, this is a big improvement. Most hitters aren’t good at finding the barrel outside of the zone, and Murphy is no different. If you chase less frequently, you take away opportunities for more whiffs and barrel suppression.

As a hitter, if you get better at targeting locations where you know you have more room for error in terms of getting your barrel to the ball, then you can move your batted ball profile towards its optimal form. And that is exactly what Murphy has seen happen so far this season. For the first time since his cup of coffee debut in 2019, he is pulling half of his batted balls (50.7%). In the previous two full seasons, he pulled the ball 39.7–41.5% of the time. Pulling the ball isn’t always the right prescription for every hitter; for some, it risks too much top spin that can drag down your batted balls in the air, or it can mean not making contact when your bat path is in an upward trajectory (rolling over). But Murphy’s best contact has always come when he pulls the ball. Below is a table of all of Murphy’s batted balls greater than or equal to 95 mph and between an 8–32 degree launch angle; the former is Statcast’s definition of hard hit, and the latter is its definition of the sweet spot:

The most ideal way to display this data would be bucketing by spray angle, rather than using Statcast’s directional definitions, but that data is not publicly available. If this were separated by spray angle, it’d be easier to see that batted balls to the left side of the field are most ideal for Murphy. Either way, the percentages clearly show that he doesn’t have the kind of opposite field power that would justify trying to make that a main part of his game. His best chances of hitting the ball hard in the air is by hitting it to the left side. The following spray chart shows you what this group of batted balls looks like on the field. (The venue chosen for the dimensions is Truist Park.)

If you couldn’t see it on the table, you can definitely see it here: Murphy’s home run power is from the pull side gap to the left field foul pole. Unfortunately for him, this wasn’t ideal for a right-handed hitter in Oakland. According to Statcast’s park factors, Oakland Coliseum has been the third-least hitter-friendly park for right-handed hitters in the last three seasons in terms of wOBACON, whereas Truist ranks seventh. And while home/road splits analysis doesn’t always tell the entire story of a hitter, Murphy’s 106 wRC+ at Oakland compared to 126 elsewhere during his tenure there is notable. Perhaps he feels more comfortable with this approach in his new home, but no matter what, it’s clear this is something that should be a permanent change.

Typically, this is the point in a piece where I introduce mechanical changes as a complement to the swing decision and batted ball analysis. But when I was watching Murphy’s tapes from this year and last year, he didn’t look all that different. See for yourself: The first three swings are from his final month in Oakland last year, and the other three are from his first month in Atlanta, all on fastballs in the heart of the plate:

2022 Swing 1

2022 Swing 2

2022 Swing 3

2023 Swing 1

2023 Swing 2

2023 Swing 3

The setup and finish are both very similar, the leg kick hasn’t undergone any significant changes, and the stride direction is almost identical. All I can say is that things look smoother and more connected. There might be slightly different timing mechanisms going on with the leg kick that has led to a more connected swing between the upper and lower body, but again, there haven’t ben any significant changes. That tells me that the change in swing decision is the leading factor in this early hot streak.

As hitters get older, they often better understand who they are and what their swing can do. There are multiple variables at play with Murphy, but it seems as if he has gotten to the point where he understands the exact approach he needs to have to be the best version of himself. We’ve seen this happen with hitters in Atlanta before, and he is most likely another example. Will pitchers adjust to his changed approach? Probably; that’s just life in the big leagues. But from his perspective, it can take years to get to this point where you know your recipe for success. Even when he sees his inevitable regression from his exorbitant .340 ISO, he will still know what his blueprint is to optimize his profile, and that is huge for himself and his team.

What makes you happy? Among the things that bring a smile to my face, talking about catching is up there. I will look for any excuse to write, talk, or think about catcher defense. I’m one of those people that has missed catching bullpens since I’ve stopped playing regularly. For those of you who do not know, that is not normal! So whenever Statcast drops new information about catcher defense, I have to write about it.

A few weeks back, I covered some catchers who were throwing at a rate that suggested additional defensive value relative to their peers in the new, more aggressive stolen base environment. Soon thereafter, MLB.com’s Mike Petriello revealed a new stat, Caught Stealing Above Average, to the public, and that Baseball Savant would roll out a leaderboard that would offer a more objective look at throwing out runners relative to the traditional caught stealing stat. You can check out the full leaderboard here.

There are multiple components taken into consideration for Statcast’s model that try to even the playing field when it comes to throwing out runners — variables like pitcher delivery speed, a runner’s lead and jump, and more. Evening all of those out provides more insight on how some catchers are more deserving of outs than others. Typically, I would highlight the catchers who have excelled at throwing out runners, but to emphasize the value of this statistic, I instead want to look at those who have been unlucky this year and last despite consistent strong throws, as well as other catchers where the trends are concerning. The first of this group is expected but notable nonetheless:

J.T. Realmuto (1 Catcher Caught Stealing Above Average in 2023, no. 7)

Base stealers have been running like wild against the Phillies this season, and it’s made for some confusing statistics for J.T. Realmuto. Out of his first 17 stolen base attempts of second base, he’s only caught five runners. If you remember this piece back in November, you know Realmuto has one of the strongest arms and fastest pop times in the game; if anybody should be throwing out most runners, it’d be him. But this year, he is only running a 29% caught-stealing rate, partially due to plays like the one above, where his pitcher was just slightly too slow to home. He has still been better than his expected rate of 22%, but his bar is much higher than any catcher in the league.

Realmuto’s 2022 track record is even more impressive than this year’s. If you combine all of last season’s attempts with this year, his CS% sits at 48%, with an estimated CS% of 23%. His laser-quick pop time makes up for his slower-to-the-plate pitchers. Realmuto is elite at throwing, framing, and blocking; nobody else can make that claim to this extent. We are watching one of the best defensive catchers of his generation.

Shea Langeliers (2 Catcher Caught Stealing Above Average in 2023, no. 5)

Not many things are going right for the A’s, but Shea Langeliers has impressed on both sides of the ball. With a 109 wRC+ fueled by a .244 ISO, he is off to a solid start with the bat, and both his swing and power are promising. On the defensive side of the ball, he has averaged a 1.95 pop time but has been a little unlucky with throwing out runners, with a CS% in his first 19 attempts to second base of 32% but an estimated mark of 24% — a similar discrepancy as Realmuto. On this throw, he was as perfect as you can be, but his pitcher was dragging his feet to get the ball home, and Tony Kemp lost his glove on the tag anyways.

While the pop time isn’t elite on average, Langeliers has proven that he is accurate enough to throw runners out if given the opportunity. It’s one of those situations where he isn’t necessarily a top tier thrower and therefore doesn’t have much room for error if his pitchers don’t cut him some slack or if his throw is just slightly off line. To me, Langeliers is the type of catcher who offers a glimpse into the future. With some automated ball-strike system inevitably coming to MLB, his profile is one that would perfectly transition to that new reality, as he is only average at blocking and framing but is slightly above average at throwing. Combine that with above-league-average offense, and you have yourself a perfect prototype for the potential new catching environment.

Martín Maldonado (2 Catcher Caught Stealing Above Average in 2023, no. 4)

If it weren’t for Realmuto, Martín Maldonado would find himself atop the new throwing leaderboard from 2022 through today, with seven CS Above Average. This year is no different, as he holds a 33% CS% despite a mere 14% estimated rate. The pitchers in Houston aren’t helping him, but he is nabbing runners regardless. Case in point: the play above, where Cristian Javier’s big leg kick and loopy arm took up too much time, undermining Maldonado’s pinpoint throw. But even when he isn’t catching runners, he is making it close.

Over the past few years, I’ve gone back and forth on the Astros’ decision to use Maldonado as their primary catcher. He is an incredible fielder but is consistently one of the worst hitters in the game. As his framing skills have undergone a slight regression compared to earlier in his career, it’s statistically unclear if it’s worth keeping him as the mainstay. But the additional data on Maldonado’s elite throwing and blocking in the last few months reminds us why he’s the lead catcher in Houston. Combine that with his glorified intangibles, and you can easily understand why he has cemented himself as the starter despite the lack of offense.

This new information can work in the other direction, too. Sometimes catchers are unlucky because their pitchers put them in a hole, and other times they can be even worse than expected. Unfortunately, there are some promising young catchers who fall into the latter category. Keibert Ruiz is 2-for-17 (12%) to start the year despite a 23% estimated CS%. His plus-2.00 pop time is the main reason for this. If his framing continues to trend in the wrong direction along with his arm, he will need to be an above-average hitter to live up to his prospect pedigree. Francisco Álvarez faces a similar dilemma, going 0-for-12 to start the year. His estimated CS% was only 12%, but his throws have not been competitive regardless.

For a while, catching was a semi-mystery; we knew who had rocket arms and who didn’t. Now, we have information about framing, blocking, and throwing that helps us figure out the true value of a gifted defensive catcher. It’s an exciting time to be a catching fanatic.

While I’m sure those of you who are reading this should be aware of what I’m about to say, I’m going to say it anyway: hitting baseballs is difficult. In fact, it is the very reason I’m writing this piece. As I’ve watched the beginning of the season, I’ve noticed some hitters make tweaks here and there. Hitting is a game of adjustments; if one thing doesn’t work or doesn’t feel comfortable, you try the next, and so on and so forth until something clicks. When you’re struggling at the plate, there are some rules of thumb to consider if you’re considering a change. The first thing that comes to mind is obvious: simplify.

There are a few ways to interpret that, but what I have in mind focuses on a hitter’s load. Depending on factors such as bat speed, barrel acceleration, and pitch identification, a hitter will fall somewhere between Javier Báez and Giancarlo Stanton on the movement spectrum. By that, I mean that you can move almost every part of your body, or you can just pick your bat up off your shoulder and swing. Neither is necessarily better than the other, but for some hitters, too much movement (or movement in an inefficient direction) can negatively impact bat path or the ability to make flush contact on a consistent basis. An adjustment which simplifies your load can make it easier for a hitter to get the bat on plane with the baseball. Read the rest of this entry »

One of my favorite articles from the offseason was Ben Clemens’ piece about Gerrit Cole. It’s a thorough explanation of why and how Cole is still one of the league’s best pitchers, this despite a down year and public perception that several others had surpassed him. Through the first few weeks of the season, we’ve gotten strong reassurance that Cole is indeed still one of the best pitchers in the sport.

Cole has been fantastic through five starts and 34 innings pitched, with a 0.79 ERA, a 2.21 FIP and — get this — zero home runs allowed. That last point is the most important one. Last year, no pitcher in the majors gave up more home runs than Cole (33). It was his kryptonite the entire season. He would be coasting through a game, striking out 29.3% of the batters he faced, and then suddenly a ball would find itself in the seats and his start would blow up in front of him. His longest stretch without giving up a long ball in 2022 was three games, a feat he managed on two separate occasions. But this year, he seems to have turned the corner. The key to Cole’s success during this turnaround has been his fastball. There are a few things contributing to this that tie in with one another, but I’ll start with his four-seam fastball location:

Cole has been excellent in keeping the ball up on his arm side both in and out of the zone. You can see that in the heat maps, but if it helps to know, 32.4% of his four-seam fastballs have been in the upper third of the strike zone, or above and to either side of the upper third. Last year, that mark was only 21.1%, the lowest it has been since before his breakout year in 2018 with Houston. Cole has one of the best four-seam fastballs in terms of velocity and stuff; if he locates the pitch in its ideal spot up in the zone, it’s extremely difficult to hit. The following two pitches are great examples of how hard it is for a hitter to get on top of a precisely located, high-velocity fastball with ride:

Vladimir Guerrero Jr. and Matt Chapman have been two of the best hitters in baseball this year in terms of both hard contact and results. Both are routinely crushing fastballs. Yet neither was able to get their best swing off due to Cole’s location. Even the best hitters can’t square up Cole when his fastball command is on. That’s perhaps an obvious statement, but it’s necessary to point out. It’s why he broke out with Houston and why he has been one of the most productive pitchers in baseball over the last five seasons. The question, then, is how he returned to having great fastball command. For that, I’ll turn to some information on his release point and extension.

It’s a simple concept. If you want to more precisely target a specific spot in the zone with a pitch you throw half the time, then alter your release point to set yourself up for consistent success. Cole is releasing the ball higher and closer to third base than he ever has in his career, and with the least extension he’s gotten down the mound since his Pittsburgh days. You might be thinking that’s counterintuitive. Typically, a four-seam fastball’s qualities will be the best with more extension and a lower release point, and you’d be right to think so! However, there is some nuance to consider with Cole’s situation.

So far, this is the least amount of induced vertical break (IVB) he has had since joining the Yankees, but a sacrifice in IVB due to an altered release point and decrease in extension has allowed him to have pinpoint command. If you want to learn more about IVB, check out Justin Choi’s incredible piece from last year, but as a quick refresher, it’s essentially the movement that causes a fastball to “rise” relative to a hitter’s expectations. It’s not like Cole’s fastball is suddenly bad — it’s still sitting at 17.6 inches of IVB, a -4.4 degree vertical approach angle (VAA), and 96.8 mph average velocity. The IVB is still well above average. His VAA, the angle at which a pitch enters the zone, is still flat enough to fool hitter’s expectations. And the velo is still top notch! Basically, the sum of the parts still makes for an elite, 99th-percentile pitch, especially when you add the command improvement. The .141 batting average against and -9 run value he’s accrued (-8 last year) prove the sacrifices are paying off.

Cole’s improvements in the top of the zone are having effects elsewhere, too. If I were a hitter facing Cole, I’d be forced to focus my eyes up and nowhere else. You have to pick your spots against a pitcher of this quality. If you don’t hunt the fastball in its most frequent location, you’re going to get beat by it over and over again. Because of that, when Cole does target the bottom of the zone, it’s unexpected — and it’s freezing hitters. He has only thrown 51 total fastballs at or under the bottom third of the zone, but 21 (41.2%) have gone for called strikes. That’s up 10 percentage points from last year and is the highest mark since his 2018 breakout. It doesn’t matter who you are, covering 97 with ride at the top and bottom of the zone is nearly impossible.

Other than the four-seam fastball itself, Cole has made some other tweaks here and there that have contributed to his resurgence. The first is how aggressive he is in 0-0 counts. To put it plainly, he is attacking hitters. The ace has never been within three percentage points of a 70% first-pitch strike rate, but this year, he is at 71.5%. It’s not just from his fastball either; he is using his curve as an 0-0 offering in the zone more frequently than last year. In general, he has continued the uptick in curveball usage that we saw at the end of last year. That’s also in line with Cole’s general willingness to be more adaptable with his pitch usage on a game-to-game basis. This year, he has used his fastball as much as 64.2% of the time and as little as 42.3% of the time. Better command and less predictability keeps hitters honest.

When you’re a great pitcher who hasn’t seen any notable decline in the quality of your stuff, you’re typically a safe bet to regain elite form. At Gerrit Cole’s level of talent, it doesn’t take a dramatic overhaul. A slight adjustment in release point was all he needed to be the top-of-the-zone killer he had been in the previous four seasons. That, along with strategic in-game adjustments, suggests there is no regression coming any time soon.

Depending on your perspective, it’s a very fun time to be a catcher. Admittedly, I may be imparting some personal bias here since my favorite part of catching was always when a runner took off for second base. It’s the one time in a game when the catcher is in the spotlight. Most of your time as a backstop consists of serving your pitcher in whatever way they need, but with the increase in stolen base attempts this year, catchers have consistently found themselves with golden opportunities to show off their throwing skills. Because of this, arm strength and pop time are as important as they’ve been in the last few decades, and some catchers have been early standouts when it comes to controlling the running game.

The importance of throwing out runners, or even limiting attempts, has made a comeback. As we progress through the next few months, we’ll gain a more precise understanding of just how valuable this skill can be in this stolen base environment, but the early season trends indicate that if you can throw out runners at a good rate, you’ll be one of the most valuable defensive players in the league. And there are a few catchers who have stood apart from the rest of the field when it comes to this being a significant part of their overall value so far. I’m going to highlight two of them in this piece. The first is Gabriel Moreno.

Through the first few weeks of play, no player has produced more defensive value than the young catcher in Arizona and much of that is due to his success throwing out runners. In Moreno’s 2022 prospect report, Eric Longenhagen reported that the catcher sat in the 1.95-1.98 pop time range while in the Arizona Fall League. That would have been slightly above the big league average. However, so far this season, he has been excellent, averaging 1.90 seconds according to Baseball Savant. The combination of his pop time and five caught stealing in eight attempts (63%) has provided the D-backs with plenty of fun, but also with the reassurance that their catcher can still provide value despite struggling offensively (he has posted a meager 62 wRC+ in 52 plate appearances).

After just two weeks of play, there are several hitters off to scorching hot starts. Some are expected; for example, Giancarlo Stanton, Freddie Freeman, and Mike Trout all have xwOBAs over .460 so far. Given their vast history of offensive prowess, it’s not surprising to see them put together a stretch like this. But if you look near the top of the xwOBA leaderboard, you might do a double take when you see some of the names aside those aforementioned stars. Without larger batted ball samples, we may not be able to draw any concrete conclusions about the unexpected players, but there are some sticky traits that are worth paying attention to as the season develops.
